RiNG FOR SPINNING-FRAMES.

SPECIFICATIGN forming part of Letters Patent No. 288,932, dated November 20, 1883,

Application filed February 13, 1883.- (No model.)

To all whom it may concern:

Be it known that 1, CHARLES LAWRENCE LINCOLN EMERY, of Biddeford, in the county of York, of the State of Maine, have invented a new and useful Improvement in Rings for Spinning-Frames; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure 1 is a transverse section of a spinning-frame-ring rail and one of my improved rings adapted thereto. Fig. 2 is a side view, and Fig. 3 an under side View, of the eccentric necked traveler-ring and its eccentric ring, to be described, the said figures being on an enlarged scale.

The nature of my invention is duly set forth in the claim hereinafter presented.

In the traveler-ring A the outer surface of the neck a is the periphery of a conic frustum, and is eccentricwith respect to the race 6, and extends downward from an annular shoulder, c, or base of the ring, which, when the ring is in place in the ring-rail B, rests directly upon the upper surface of such rail. The said eccentric neck ahas its greatest diameter at its lower end, and is encompassed by an annulus, C, which is split transversely, as shown at d, to enable it to be readily sprung upon or off the neck by manual power. The external surface of the annulus is eccentric with respect to that of the neck, and is the periphery of acylinder, the internal. surface or bore being conical or tapering, so as to fit to the tapering external surface of the neck.

The object of making the outer surface of the neck and the inner surface of the accompanying ring tapering, as represented, is to so engage the two rings as to enable the outer to be revolved on the inner of them, and to prevent their disengagement while the outer ring may remain unexpanded. By such means the outer orsplit ring, while encompassing the neck of the inner ring, cannot be accidentally detached therefrom.

In providing a travelenring with an eccentric neck and an expansive or split eccentric ring adapted thereto, for the purpose of adjustingthe race into concentricitywith the spindle it, as I understand, has been customary to provide the split ring at top with an annular shoulder or flange to rest upon the ring-rail, the base or shoulder of the traveler-ring resting in such case upon the flange of the split ring.

With my improvement I entirely dispense with a shoulder or flange to the split ring, and thus am not only enabled to have the race nearer to the ring-rail, whichis an advantage, but to materially lessen the cost of making the split ring.

To centralize the race to the spindle, the split ring is to be revolved on the eccentric neck of the traveler-ring, after whichboth the traveler-ring and split ring are simultaneously to be revolved within the socket of the rail, all of which will be readily understood by spinners accustomed to the use of traveler-rings having what are termed eccentric necks, and split flanged and eccentric rings applied to such neck. The rings are held in place in the ring-rail by a screw, F, screwed into the latter and against the split ring.

I am aware that a traveler-ring has been provided with a neck made in the shape of a conic frustum, and that the split-ring has been sprung around this frustum; but in this device the ring isprovided with the usual shoulder, the neck is not within the rail, but rests on the split ring, and the split ring is simply provided above the rail with a recess in which the neck of the traveler-ring fits.

I claim The traveler-ring A, having the race I), shoulder c, and the neck a, the outer surface of the neck being eccentric to the race, and the periphery of a conic frustum having its greatest diameter at its lower end, and the. shoulderless split ring 0, itsexternal surface being eccentric to that of the neck a, and its internal surface corresponding to the external surface of the neck, in combination with the rail B, the shoulder c, resting on the rail, and the neck a and ring G being within the rail, whereby the use of a shoulder on the ring 0 is dispensed with and the ring and neck are held together, as set forth.

CHARLES LAWRENCE LINCOLN EMERY.
